This invention relates to stamping or' marking devices, and more particularly to the tread or grain side of an outsole, the

proper. positions to start and end the outseam in the manufacture of boots and shoes.

Preferably the invention is embodied m a skivingmachine of the generaltypeshown in the application for Letters Patent of the United States, filed June 11, 1917 gerial No. 174,027, by the present inventor, since a vmark for the purpose described may most conveniently be made when-the outsole 1S:

skived. c

It is an important desideratumin the man ufacturing of high grade Goodyear welt shoes that the outseam start and end at particular points backfof the breast line of the outsole such that the outseam stitches will extendto the ends of the welt but not into the line of the heel seatnails. When'the outseam is so located the" forward pbrtion of the heel, when properly attached to the shoe, will extend sufii'ciently over the rear ends of the outseam to adequately coverand protect them, As the outsole completely covers the welt and the shoeis sustained in an inverted 'positlon during the outseam stitching operation, the ends of the welt are hidden at this time and this renders it diflicult for the operator to accurately de tel-mine the correct points on' the outsole to start and end theoutseam. I v

Accordingly, the object of the present anvention is the provision of adistinct mark, pl

line or other indicia to indicate the correct position to start and end theoutseam whichwill be in full view of the operator when the shoe is'inverted for sewing the outseam.-

The machine shown in said-copending application is provided with a die roll having a matrix and a cooperating feeding and bodiment of the invention the matrix is so 7 designed as to effect the skiving of the shank of the outsole on its'fiesh side, in such a manner thattherear ends of the skived portions extend a certain distance to the rear of the breast line of the outsole. As the pro c e p'oints'to start and end the outse'am are at a certain distance tothe rear of'the breast line 7 of the 'outsole,jwhich distance is dependent upon theslze of the sole, the die roll may conveniently be utilized to locate amark on y the outsole which will be inview of the operator of the outsole stitcher and in a po sition to accurately determine the'points to start and end the outseam. Accordingly, a feature of the present invention resides in providing the die roll with a suitable mark-- 'ing device so located -on'-its matrix that as thesole is skived it also will be stamped or marked on its grain sideat a point whichwill indicate the proper location of the ends of the outseam.

Tothe accomplishment ofthe above-object the [invention comprises the features and combinations of parts hereinafter described and particularly claims. .o

The invention as applied'to the lskiving machine of said copending application is pointed out in the appended illustrated in theaccompanyingdrawings, in

which ;Figure 1 is longitudinalsectional 1M 7 view of a skiving'machme embodying the in-- VGntlOIl which view corresponds generally p to Fig; 4 of said copending application; Fig. 2 is detail-front elevation of a matrix or matrix sleeve for the machine with the novel sole marking device mounted thereon; and- Fig; 3 is aview of a portion of the grain side of an outsole 'havingindicated thereon, by

dotted lines, the outlines of the skived portions of the shank and by a heavier dotted line the location and preferred form of the mark for. determining the start and end'of the outseam.

The machine shown in the accompanying r a drawings has the same general construction and mode of operatlon as the machine dlsmounted thereon, and a'feeding and pressure I, roll 14 to assist in feeding an outsole between the rolls and to forcethe outsole into ,the matrix The' skiving knife 16 is constructed and arranged to coiiperate with the matrix and pressure rolls to skive off marginal portions 18- 18 (Fig. 3)}of the shank '7 of the outsole. The outsole is presented to invention" is equally applicable to a matrix V fl made in sections; for axial adjustment. t i

the shank of the outsole are determined by the rolls means of the solefeeding carriageEQO having the heel gage 22, and is guided by the ball line gage24 and the breast line gage 26 during its feeding movement. Referenceis: hereby made to said copending 1 application for a' det-ail descrip'tion of the parts abovereferred to and their mode of operation. It will be noted, however, that for simplicity of illustration the improved matrix 12is shown Without the provision for I axial adjustment illustrated and described 2 5 in said copendingapplication, although it will beobvious from the following descrip tion that the marking device of the present The rear ends of the skived portions of the location of the shoulders 28'28 on the matrix, and in the machine illustrated-"in the drawings said. shoulders are properly '3'5 llocated; angularlyito position said rear ends atfi'the preper distance to the rear of the 1 breast; line of-the-outsdle. As each end of 1 the outsea-m should extend" to a "definite point at the-rear of the breast line, the marking device embodied; in the illustrated machine has been located substantially in Valinement with; the shoulders 28- 28., The marking device,cas shown,-comprisesa series of pins" 30 radiallyembec ld'ed' inthe matrix and extending in 33. lineparallel to the axis ofvthe die. roll 10, havingtheirprojecting ends sharpened. to impress atransverseline 32 on the grain side of the outsole; after the completion of the skiving 0138111131011. It will be seenrthat by thus mounting the" marking 7 device ongthe die roll'of a skiving machine,

which skives an outsole to a particular line relativeto the size of theso'ile, the correct positions to startand" s end the outseam f "the operator of the ioutsole"stitching ma-q "ch-in'e. i

vention' having been indicated and the pre-] v ferrediiembodiment of the, invention "having stitches willbe indicated "with the utmost accuracy by; a line-distinctly impressed on the grain side of the outsole in full View of TheQnatu-reand'scope oftthe present inbeen'specifically described, what is claimed as newis 1. A 7 machine of the class described,having.

incombination,-'a die roll having a matrix, a

pressure roll for forcing a blank into the matrix, a'skiving knifeumounted to cooperate with said rolls to skive the blank, and i of an outsole; into the matrix, a skiving knife to act on the flesh side of the outsole to skive said shank,and a marking device mounted on the die roll to mark on the grain side of the outsole thepositions to start and end the outseam.

'3. A nachine of the class described having, in combination, a die roll having a matrix,.a pressure roll for forcing the shank of "an out'sole into the matrix, a skiving knife to act on the. flesh side of the outsolc to skive said shank, and a marking device mounted on the die roll to effect after the skiving operation an impression on the grain side of the oiutsole to mark the positions to start and end the'outseam.
